I weighed mine (stood on scales, then held the bike) and took a better photo, sans saddle bag, lights, bell and the fly that was previously resting on the saddle. 7.4kg with the 105 group set and 54cm frame, so not a fairly big one. I'm not sure I could get it down under 7.0kg. I'm thinking about doing a Di2 upgrade - I can get that at a good price. Won't necessarily make it lighter, but it appeals to the gadget freak in me.

If you want bland, I've built a 7.2kg Chinese carbon. It's mostly lightly used second hand parts and bits I had lying around, it rides nicely and has allowed me to beat my best times on the local climbs

Not bad for $800....(in the time honoured tradition of bike builders everywhere, I haven't included the cost of the parts I already owned)

Heres my Scott Foil 20, picked up a set of Zipp 606's i scored off ebay at a good price i think. never had full carbon wheels before and i'd wanted a set of 404's for awhile, but an 808 rear looks mint as on it, and they go well with the zipp bar and stem. the decals are abit scruffy so i might change them for the beyond black style as that will look pretty stealthy i reckon.now i just need to scrounge another cassette and get some suitable pads and see how it rides, hopefully tommorow and ill get it weighed at the same time. with my old alloy mavic wheels it weighed 7.1kg so would be nice to see it under the 7kg mark.

My Giant is about 6.9kg with rear light on it and the Garmin 800 fitted to it:

Excuse the odd front wheel, my other one was off getting a small chip in the edge of it repaired. I've got it back, have yet to photograph it. It rides very well and is a lot smoother across the bumps than my Trek Madone 4.5.

Very nice. i used to have a 20 but it never looked that mean.Love the fat rear end.

That is a sweet looking bike.

I don't understand how it can be so light, though. I can't tell if the bars are carbon (I assume so), and I don't know exactly how much those wheels weigh (but they are fairly deep, so probably not super light). Are the wheels very light (say 1300g)? Every other part on the bike looks like it would be similar to or heavier than my self-built Chinese framed bike, which comes in at about 7.1kg excluding my Garmin. I would be happy to say that my scale is over-estimating, but I have calculated the weight of all the parts and come in within 50g of my measured weight. If it just comes down to the wheels, I will be content, because it will mean that I am doing the best I can on my bike without a BIG additional cost.

I could get under 7kg on mine by changing to Conti supersonic tyres, but I prefer a little protection and GP4000s are not exactly boat anchors.

I will post a build list and photos over the weekend looking for advice.

Great looking bike there mate! Can you do me a favour and tell me the length of the bolts holding the battery mount on the non drive side chain stay? i believe they'll either be 16mm or 10 mm. I have an SL 1 and am looking swap the mechanical bits to Di2.

Adamr build list?

My chinese carbon framed light weight build came in at 6.4kg without much effort (including pedals and speed cadence sensor but not my Garmin 705), had issues with the drivetrain (ended up being the new chain did no like either cassette on my two wheelsets) and ended up stripping it to build a light weight alloy crit bike (which is almost finished - Pawnii pics of the Canyon soon I promise and that should be about 6.6kg)

No as attentive to detail as Pawnii, as I did not measure offcuts. But otherwise my build list with parts measured on kitchen scales was within 2% of my luggage scales used to measure bikes

Total, including minor bits and pieces and estimate of grease etc calculated at 7071g. My luggage scales show about that, but they are not precise. That includes pedals and cages, but not lights or Garmin cadence sensor or mount.

I am as light as I can go on brakes, and nearly as light as I can go on saddle. Obviously, I could save a bit with a SRAM Red or Force group set, but I don't like double-tap, so I am willing to accept a weight penalty for that (estimate 150g). Cranksets don't get much lighter for a british threaded bottom bracket. I could easily (but expensively) save about 70g on new handlebars and stem. I know I could save 250g on some chinese 38mm carbon clinchers.

I have priced up changes to get to 6450g, but that would cost $1300. Those changes include changing to Continental Supersonic 23mm tyres, which I am not keen on (even though it would save about 160g).

If I went for ultra-light tubular wheels, I could get to about 6200g, but that is not practical for me, either.
